Introduction:
With the UK government banning disposable vapes in 2025, many vapers are looking for more advanced alternatives. Sub-ohm vaping is one such evolution that has gained traction. If you’ve been considering a move beyond your disposable or basic pod kit, this guide will walk you through everything you need to know.

- How it works
- Whether it’s the right option for you
What Is Sub-Ohm Vaping?
Sub-ohm vaping refers to using a coil with a resistance of less than 1.0 ohm (Ω). This differs from the standard coils in traditional pod systems, which typically have resistances above 1.0 ohm. Sub-ohm coils, generally between 0.1ω and 0.8ω, allow for more power and, as a result, greater vapour production.
Why It Matters: A lower resistance means more power flowing through the coil, which in turn generates more heat. The result? Larger clouds of vapour and a more intense vaping experience.
How Does Sub-Ohm Vaping Work?
Sub-ohm vaping is all about the flow of electricity. Here’s how it works in simple terms:
Lower resistance lets more current flow: Imagine opening up a water pipe. More water can flow through with less restriction.
More power: With more current, the coil receives more power, making it heat up faster.
More heat equals more vapour: A hotter coil vaporises e-liquid at a higher rate, which means bigger clouds.
Mesh coils are commonly used in sub-ohm devices. Mesh coils are a game-changer for sub-ohm devices. They have a larger surface area, which allows for even heat distribution. This results in better flavour and a longer lifespan for the coil.
What’s It Like to Vape Sub-Ohm?
If you’ve never tried sub-ohm vaping, get ready for a completely different experience. It’s worlds apart from traditional pod kits. Here’s what you can expect:
Bigger clouds: Sub-ohm setups produce significantly larger clouds of vapour.
Warmer vapour: The vapour tends to be warmer and smoother.
Richer flavour: Sub-ohm vaping offers a richer, deeper sensation.
Direct-to-lung (DTL) draw: Unlike the mouth-to-lung (MTL) style, sub-ohm devices are designed for DTL.
Compared to pod kits or disposables: The difference is night and day.
This means you inhale the vapour directly into your lungs, much like taking a deep breath.
Sub-Ohm vs MTL: Which Is Right for You?
Here’s a quick breakdown of the two major vaping styles:
| Feature | Sub-Ohm (DTL) | MTL (Pod Kits) |
|---|---|---|
| Vapour Production | High | Low |
| Nicotine Strength | 0mg to 6mg | 10mg to 20mg |
| Draw Style | Open lung inhale | Tight mouth-to-lung |
| Ease of Use | Moderate | Easy |
| Cost | Higher | Lower |
If you’re into big clouds and intense flavour, sub-ohm is your go-to. But if you prefer a simple and discreet option, MTL is likely better suited for you.
Essential Equipment for Sub-Ohm Vaping
To enjoy sub-ohm vaping to its full potential, you need the right setup:
Sub-ohm tank or pod: This is where the e-liquid is stored and where the low-resistance coil is housed.
Regulated mod: A regulated mod powers your sub-ohm tank. Look for one that offers at least 30 watts of power.
Mesh coils: These are standard for sub-ohm vaping. They’re more efficient at heating e-liquid and provide smoother, more even flavour.
Adjustable airflow: Essential for a customizable vaping experience.
What E-Liquid Should You Use for Sub-Ohm Vaping?
Here’s where many vapers go wrong, especially if they’re new to sub-ohm. For the best results, use e-liquids with a high VG (Vegetable Glycerin) content. This is crucial because:
VG helps produce thicker vapour: It’s responsible for the cloud production that sub-ohm vaping is known for.
Recommended VG/PG ratio: Look for 70/30 VG/PG or higher. Avoid anything with too much PG, as it can result in a harsh experience.
Understanding Nicotine Strength for Sub-Ohm
Unlike pod kits, sub-ohm vaping requires lower nicotine strengths due to the large amounts of vapour produced with each puff:
Recommended nicotine levels: Stick to 0mg, 3mg, or 6mg for a smoother vaping experience.
Avoid high-strength nic salts: These are too harsh for sub-ohm setups and can overwhelm your system.
Costs and Maintenance: What to Expect
Sub-ohm vaping is more expensive than using a pod kit, but it offers a richer experience:
E-liquid consumption: Expect to go through more e-liquid, 5 to 10ml a day is typical.
Battery life: High-wattage sub-ohm devices drain batteries quickly, so plan to charge once or twice a day.
Coil lifespan: Coils last 5 to 10 days, depending on usage and the type of e-liquid you use.
Pros and Cons of Sub-Ohm Vaping
Pros:
- Big clouds and strong flavour
- Smooth, warm vape with less throat scratch
- Ideal for cloud chasing and flavour chasing
Cons:
- Higher e-liquid consumption
- Frequent coil replacement
Not discreet, large clouds may not be suitable for public spaces
Who Should Consider Sub-Ohm Vaping?
Sub-ohm is perfect for you if:
- You’ve already used a pod kit and are ready for a more satisfying experience.
- You prefer larger clouds and a more intense flavour.
- You’re using lower nicotine levels or want to reduce nicotine intake.
Who Should Avoid Sub-Ohm Vaping?
Sub-ohm is not for everyone. You might want to stick with pod kits if:
- You’re a beginner just starting with vaping.
- You rely on high nicotine strengths (10mg to 20mg).
- You prefer a tight, cigarette-like draw.
- You need something discreet for public places.
Common Mistakes When Switching to Sub-Ohm Vaping
Here are a few things to avoid when you first switch:
- Using too high a nicotine: Stick with 0-6mg nicotine to avoid an overwhelming experience.
- Not priming your coil: Always saturate your coil with e-liquid before use to avoid dry hits.
- Vaping at too high wattage: Start low and gradually increase wattage to prevent burning coils and harsh vapour.
Sub-Ohm Vaping Safety Basics
Use a regulated mod: These mods come with built-in safety features.
Understand safety features: Look for mods with short-circuit protection and overheat protection.
Check your batteries: Always inspect for wear and tear. Replace damaged batteries immediately.
Prime your coils: Saturate your coil before using to prevent dry burns.
Stick to reputable UK retailers: Always buy from TPD-compliant retailers for safety.
Conclusion: Is Sub-Ohm Vaping Right for You?
Sub-ohm vaping offers a satisfying experience with massive clouds, enhanced flavour, and a smoother vape. But it’s not for beginners or those seeking simplicity. If you’re ready to step up from pod kits and enjoy an enhanced vaping journey, sub-ohm could be the next best move.
